Solution

The correct option is B Orchids
Orchid seed is a non-endospermic seed, i.e., endosperm is absent in it. Endosperm is a nourishing tissue present in the seed which nourishes the developingembryo. In orchid seed endosperm is absent because it is used up during the time ofseed development. Nourishment for germinating seed is provided by the food material present in cotyledons.

Rest of the options are examples of endospermic seeds.
